Retractable cantilever rack support

摘要

A removal system for membranes in a membrane filtration system of the type where the membranes ( 12 ) are supported on a membrane support rack ( 13 ) in a tank or vessel ( 6 ) which, in use, contains liquid to be filtered. The tank ( 6 ) comprises a selectively operable opening ( 9 ) which in an open position allows the removal of the membranes ( 12 ) from the tank ( 6 ). The membrane support rack ( 13 ) is movable relative to the tank ( 6 ) to move said membranes ( 12 ) through the opening ( 9 ), in its open position, to a position outside the tank ( 6 ).
